Phase Indicator Configuration Tab
The Phase Indicator Configuration tab is as shown in Figure 4-10. It allows you to
select which channel pairs will receive a phase meter on the
Metering Screen
.
Generally, it is useful to monitor the relative phase of stereo pairs. However,
sometimes each channel of a pair is unrelated to each other. This can be because
the channels are used to convey two independent monophonic signals or that one
channel may be a Center channel and the other may be a Low Frequency Effects
channel. In these instances, the Phase Indicator would almost always indicate an
out of phase condition. Because this would be a needless distraction to the
operator, switches are provided on this tab to individually turn phase monitoring for
each channel pair on or off.
Select All
and
Reset All
buttons are also provided.
